Application led December 9. 1925. Serial No. 74,275.

My invention relates to an improvement in disk Crushers and relates particularly to a vertical disk Crusher wherein a pair of opposed crushing disks are rotated in unison about a generally vertical axis. One object of my invention is the provision of an improved supporting frame for such Crushers. Another object is the provision of a suppo'rting frame in which the main attaching members are exterior to frame andmay be tightened or loosened from without the frame or housing structure. Another object is the provision of an improved supporting bearing mechanism for the opposed crushing disks and their Supporting members. Another object is the provision of improved hearing and supporting means for the rotatfng parts. Other objects will appear from time to time in the course of the specification and claims.

I is a gear secured to the flange IT and in mesh with the niiter pinion D1" on the shaft D. I is a circumferential flange upwardly projecting about the outer edge of the plate I and continued in an outwardly extending flat surface flange I1?.

Resting uion thc plate I and abutting against the ange I11 1s the removable bearing member generally indicated as K which includes a flat central apertured bottom plate KL and a circumferential upwardly turned flange K2 having an inner spherical bearing surface K3. K4 is a circumferential oil passage formed in the upper surface thereof adjacent its outer edge and K5 is an oil aperture herein shown as in register with l the oi] duct K through the plate I. K7 is a pin or other suitable securing means herein shown as integral with the memberI and adapted to pass through the plate K and to prevent relative rot-ation of the two parts. K5 is a circular oil groove in the plate I and has the short pipe K9 leading therefrom to discharge onto the ball plate H1.

L generally indicates a ball wedge meniber having a centrally depending shaft or stem L1 penetrating the bushing Gl of the eccentric E. The ball wedge is provided with a lower plane bearing surface L2 opposed to the upper plane bearing surface K1 of the plate K. Its upper surface L3 is splierically formed to conform to the lower spherical bearing surface L* of the tilting plate L5. The tilting plate is later-l ally extended as at L6 and provided with a second spherical bearing surface L7 in opposition to the spherical bearing surface K3 of the circumferential flange K2 of the plate K.

Supported upon the tilting plate L5 is any suitable crushing disk M the details of which form no part of the present invention, but which is herein shown as a generally flat late centrally apertured as at M1 and having a downwardly and inwardly turned flange M2 about the lower edge of such aperture. M3 is any suitable clamping plate therefor apertured for the passage of holding bolts M* the headslM5 of which are contained within an aperture or socket Ma in the tilting plate L5.

The disk M is further provided with downwardly depending pins or lugs Mo adapted to penetrate apertures M11 in the upper surface of the. tilting plate L5.

Formed. integrally with the flanges I11 and I12 are a plurality of bosses 'N herein shown as hollow and perforated for the passage of bolts or pins N1 screw threaded as at N2 to receive the nuts iNs. They are provided` above such bosses, with shoulders N4 against which abut thespacing sleeves N5 about the pins N1. N is an inwardly projecting dust ring resting upon bosses N7 formed in the ring N8. N is a downwardly turned flange formed about the outer edge of the ring N8 the'inner edge of such ringI extending inwardly over the portion L" of the .tiltingr plate L5. N11 is an angle ring positioned above theedgo of the ring N5 and provided with any suitable packing X12 in engagement with an opposed spherical surface N13 upon the tilting plate L5. N1* is an angle ring outwardly extending from the plate L5 and downwardly depending about the angle member N15. The purpose of these various overhanging and interlocking rings -is the exclusion of dust and grit from the opposady lll? i the bearing surfaces of tilting plate, ball wedge and supporting plate, and in general the exclusion of dust and dirt from the moving parts housed Within the interior of the Crusher.

Mounted upon the spacing sleeves N5 is perforated ring O having a lip O1 extendlng outwardly away from the sleeves N. 0s is a spring compressed heavy annular collar resting upon the ring O, its inner wall being screwed as at O. Springs Os rest upon the collar 0: and contact at their upper ends the ring O". which ring is also mounted on the pins N1. It has a downwardly extending annular wall 0'. Thel nuts Os upon the pins N1 serve to hold this collar rigidly in position so that the collar O3 may rise if the springs are compressed. while the remainder of the structure remains ina fixed position.

P is an adjusting disk plate having about its periphery an upwardly extending screwY threaded flange P in screw threaded engagement with the collar O3. The plate P is upwardly coned and has mounted on its under side the conical crushing disk 1:'2 held in position by the `collar P3. The clamping member P* is in screw threaded engagement with the nut Ps vdownwardly bearing upon the upper edge of the plate P about its central aperture. The part P1 has an outwardly extending flange Ps overhang-ing the screw threaded parts P1, and an annular protecting ring P1 hangs downwardly therefrom in slidable engagement with a part of the ring Oa to protect the screw threads. Ps are set screws in the flange P adapted to engage the ring O to lock the parts against rotation and to insure that the adjustment. will remain fixed.

The material which is centriugally dis charged from the crushing zone between the opposed :rushing disk passes outwardly beyond the spacing sleeves N5 and is received within a hopper housing formed by an outer wall R and an inner wall R1. the walls being connected by inclined bottoms R2 wherehv the material discharged into the space slides b v gravity to any suitable disposal point. R3 is a wear taking member on the inside of the wall R. adapted to receive the impact of the centrifugally discharged material. R is an Aupper connecting ring above the hopper wall R. extending between points above the'discharge from the crushing zone. where is provided an annular ring R5 extending inwardlv toward the ring O and overhanging the lip()l to prevent the xise of dust or other particles into the other part of the machine. Abovesu'ch ring is the cylindrical wall R which carries a floor R1 in -the center of *which is positioned a hopper R adapted to discharge material through the ring P to the crushing zone.

It `will be realized that whereas I have illustrated a ractical and operative device thatV neverthe ess many changes might be made in the size, shape, number and disposition of partswithout departing from the spiritof my invention and that I wish my description and drawings to s taken as in a broad sense illustrative rather than as limiting me to the s ecific showing made.

The use an are as follows:

I employ a fixed base structure generally denominated as A which has an outer upwardly projecting wall member and a central bearing supporting sleeve. Upon the ledge A1 inwardlyV projecting from the wall member rests the frame member B which includes a central vertical cylindrical sleeve C and a track supporting member C C2 C3. The securing bolts B5 are downwardly and outwardly inclined, the heads l being enclosed in the interior of the .structure and the nuts Bs being exterior. Thus, in contrast to earlier crushers cf this general type. the frame securing lneans are all external and in fact in the device as at present designed external access is had tc practically all the securing means employed.

`^ The eccentrically apertured sleeve E is centered in the fixed sleeve C and the fixed sleeve A. its vertical downward thrust being taken by the bearing bushing E5 with its outwardly projecting flange Es and its inwardly projecting flange E'. The eccentric is driven through the gear E and the gear D at the end'of the drive shaft D. Rotatably mounted in the eccentric aperture of the sleeve E is the downwardlv depending shaft L1` of the ball wedge L. This ball wedge is gyrated in response to rotation of the sleeve E its weight being su portedupon thebearing plate K. the opposed) bearing surfaces being plane. I prefer to employa chrome "anadium steel or-similar hard steel member as a ball wedge. the removable wear taking disk bein; preferably formed of a softer material,\for example cast iron. The wear taking disc is provided with a circumferential annular upwardly projectins.lr flange having a spherical hearing surface K3 adapted to receive a similar opposed spherical bearing surface upon the tilting plate member L5. VThe upper surface of the ball wedge and thelower` sur operation of my inventionY face of the tilting plate are spherical and concentric. the tilting plate being thus tilted in response to gyration of the ball wedge and being -onstrained to a tilting movement about its center by its engagement with the cession ofthe lower disk from the upper in y response to the gyration of the ball wedge and the consequent movement of the tilting plate.

In order to provide an etlicient supporting means and one which will not readily wear I employ a track ledge C2 upon which rests a plane surfaced ring H of any suitable material for example steel. Preferably the upper surface of the ring H is continued by the upper surface of the ledge oi step C3. Resting upon the broad surface thus supplied are a lurality of balls constrained to a fixed relative position by the ball ring H1. Theball ring-is supported by the balls out of contact with the track or ring H but has a slightly downwardly depending inner poi'- tion H8 which is in bearing engagement with the supporting member C3. The ring structure is held against radial movement by the upwai'd projecting C4 of the ledge C3. The upper track H1 rests upon the balls and supports the entire superstructure of the Crusher, thc superstructure being cen- (ered by thesleeve I* which rotates about the upper portion of the 'sleeve C".
